Abstract

It is shown using Mössbauer spectroscopy on ¹¹⁹Sn, ¹²¹Sb, and ¹²⁵Te isotopes that the local structure of germanium atoms changes during crystallization of amorphous Ge₂Sb₂Te₅ films (tetrahedral symmetry changes to the octahedral one), whereas the environment of antimony and tellurium atoms remains the same (the environment of antimony atoms it close to that in the Sb₂Te₃ compound).

非晶和晶体Ge 2 Sb 2 Te 5薄膜的局部结构

摘要

使用Mössbauer光谱对¹¹⁹ Sn，¹²¹ Sb和¹²⁵ Te同位素进行分析表明，锗原子的局部结构在非晶Ge ₂ Sb ₂ Te ₅薄膜的晶化过程中发生了变化（四面体对称性变为八面体）。锑和碲原子保持不变（锑原子的环境接近Sb ₂ Te ₃化合物中的环境）。
